team-rfc

team-rfc is a skill for Claude Code from ketor/cto-fleet. It costs 109 tokens per session (7,567 once invoked), scanned B, original, Apache-2.0.

A guided team workflow for researching a technical problem, designing two independent solutions, reviewing them, and producing an RFC (a structured technical design document).

In plain words
What is it for?
Use it to create Chinese or English RFCs for new features, code changes, system migrations, and integrations.
Why use it?
It reduces the effort of turning an unclear feature, refactor, migration, or integration request into a reviewed plan. It can also automate decisions or collect confirmation at defined points.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

team-rfc scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 591 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preamble (run first)

_UPD=$(~/.claude/skills/cto-fleet/bin/cto-fleet-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD" || true

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/cto-fleet/cto-fleet-upgrade/SKILL.md and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If JUST_UPGRADED <from> <to>: tell user "Running cto-fleet v{to} (just updated!)" and continue.

参数解析:从 $ARGUMENTS 中检测以下标志:

  • --auto:完全自主模式(不询问用户任何问题,全程自动决策)
  • --once:单轮确认模式(将所有需要确认的问题合并为一轮提问,确认后全程自动执行)
  • --type=feature|refactor|migration|integration:RFC 类型(默认根据需求自动推断)
  • --lang=zh|en:输出语言(默认 zh 中文)
模式 用户确认范围 条件节点处理
标准模式(默认) 需求分析确认 + 方案评审确认 + RFC 文档确认 正常询问用户
单轮确认模式--once 仅 RFC 文档确认 自动决策 + 收尾汇总
完全自主模式--auto 不询问用户 全部自动决策,收尾汇总所有决策

单轮确认模式下条件节点自动决策规则:

  • 需求边界不明确 → team lead 自行界定范围,在最终文档附录中说明
  • 两位 architect 方案分歧 → reviewer 评审后 team lead 综合裁决,收尾时汇总
  • architect 分歧 > 50%不可跳过,必须暂停问用户(熔断机制)
  • reviewer 否决全部方案不可跳过,必须暂停问用户(熔断机制)
  • researcher 报告"关键技术信息不足"不可跳过,必须暂停问用户调整需求/补充上下文(熔断机制)

完全自主模式下:所有节点均自动决策,不询问用户。仅熔断机制(architect 分歧 > 50%、reviewer 否决全部方案、researcher 报告关键技术信息不足)仍然生效,触发时必须暂停。

RFC 类型说明:

类型 适用场景 侧重点
feature 新功能/新系统设计 架构设计、API 设计、数据模型
refactor 已有系统重构 现状分析、重构策略、兼容性、灰度方案
migration 技术栈/平台迁移 迁移路径、数据迁移、回滚方案、双写策略
integration 系统集成/对接 接口协议、认证鉴权、数据映射、错误处理

解析后将标志从技术需求描述中移除。

使用 TeamCreate 创建 team(名称格式 team-rfc-{YYYYMMDD-HHmmss},如 team-rfc-20260311-143022,避免多次调用冲突),你作为 team lead 按以下流程协调。

文件交接规范(File-Based Handoff)

所有 agent 间传递详细报告时,必须采用文件交接模式(防止上下文溢出触发 20MB 限制):

  1. 写入文件:将完整报告写入团队工作目录:
    • 目录路径:/tmp/{team-name}/(team lead 在 TeamCreate 后执行 mkdir -p /tmp/{team-name} && chmod 700 /tmp/{team-name}
    • 单个文件 ≤ 2000 行;超大报告拆分为 summary + details 文件
  2. 发送引用:通过 SendMessage 仅发送(≤500 字符):
    • 文件路径(1 行)
    • 关键摘要(含核心指标/发现/评分)
  3. 按需读取:接收方使用 Read 按需读取文件,发送方不内联完整内容
  4. 路径转发:team lead 转发报告时只转发文件路径 + 摘要,不 Read 后再 SendMessage
  5. 遵从校验:team lead 收到超 1000 字符且不含 /tmp/team- 路径前缀的消息时,要求 agent 以文件交接模式重发

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

team-rfc is a skill published in the GitHub repository ketor/cto-fleet (5 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 109 tokens to every session and 7,567 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
